Abstract

The present disclosure relates to a method of inducing tissue regeneration, said method comprising administering to said tissue a composition comprising a population of mesenchymal stem cells (MSCs) and a carrier, wherein said composition possess an inherent ability to reduce inflammation by increasing levels of IL-10 and decreasing levels of TNF-α and IL-6. The present disclosure also relates to a method of treating an autoimmune disease through regeneration of cartilage and bone tissues in a subject, the method comprising: administering therapeutic amount of a composition comprising a population of mesenchymal stem cells (MSCs) and a carrier to the subject by intra-plantar route, intravenous route, intramuscular route, intraarticular route, intraosseous route, or subcutaneous route; wherein said population of MSCs is a homogeneous population having a size in the range of 15-30 μm; and wherein said composition comprises secretome of said MSCs having VEGF and IL-10.
